摘要： Systems and methods are disclosed for processing image data to provide adjusted pixel information that achieves smoothed output discontinuities. In one exemplary embodiment, there is provided a method of processing image data including analyzing first display information including pixel data indicative of pixel display on a graphical user interface, detecting one or more ramp steps in the pixel data, and assigning, in association with random number generation and/or threshold setting functionality, a carry possibility for a pixel adjacent the one or more ramp steps. Other exemplary implementations may include generating second display information included adjusted pixel data for pixels adjacent the ramp steps. Consistent with certain implementations, the second display information may include pixel values adjusted according to the carry possibility in one or both of the temporal domain and/or spatial domain.

摘要： A method of reducing mosquito noise in a digital image. As mosquito noise is often most plainly visible in the “background” of an image (e.g., the sky or some other backdrop to objects within an image), the luminance value of the background of the image is first determined. Then, the luminances of the pixels of the image are compared against this “background luminance” to determine which should be considered as part of this background. The luminances of these background pixels are then averaged so as to smooth out the representation of the background, and reduce mosquito noise.

摘要： A method and system is provided for reducing mosquito noise in a digital image. The method and system receives an input luminance value for a first pixel in the digital image, and determines whether the first pixel is in relative close proximity to an object appearing in the digital image, based on a comparison of the variation between the input luminance value for the first pixel and luminance values of a first plurality of neighboring pixels. If the first pixel is in relative close proximity to an object, the method performs an average filtering of the input luminance value for the first pixel, based on the luminance values of a second plurality of neighboring pixels, to provide a filtered luminance value for the first pixel.

摘要： The present invention provides a system and method for protecting data stored in the control registers of an integrated circuit, such as a television chip. The system and method use one or more selectively activated read protection modules to prevent the control registers from being read unless a predetermined key or password is entered. The password or key may be stored in password registers within the chip. A key access generator will enable read access of the control registers if correct values are written to the appropriate password registers. The key access generator may enable read access for a predetermined period of time or until it receives another input.

摘要： The disclosure provides a method and a device in a communication node for wireless communication. The communication node first receives first information and second information, and then transmits a first radio signal in W1 time sub-window(s); the first information is used for determining X candidate time window(s), any one of the X candidate time window(s) has a time length equal to a first time length, and the first time length is fixed; for a subcarrier spacing of a subcarrier occupied by the first radio signal, one of the X candidate time window(s) comprises Y candidate time sub-window(s), and the Y is related to the subcarrier spacing of the subcarrier occupied by the first radio signal; the second information is used for indicating W candidate time sub-window(s) out of the Y candidate time sub-window(s); and each of the W1 time sub-window(s) is one of the W candidate time sub-window(s).
